I bought an iphone 6s last year (sept,2015) directly to Apple store. I applied for the Apple Upgrade Program, which you can upgrade yearly. But when i was checking my billing statement, i noticed that T mobile is charging me for another phone that i didn't bought to them to Tmobile. It has the same IMEI that i bought directly to the Apple store, but I dont get any phone from Tmobile. Right now I have an Iphone 7 plus that i also got to the Apple store directly, got it through the Apple Upgrade Program. And still Tmobile i charging me for the Iphone 6s that i already traded in to the Apple store. Please help me! I need to know what should i do. I already talk to customer service. And went to my local Tmobile store. Please help me what to do!

I agree with tidbits. It sounds like you're on EIP and still being charged for the phone you traded in with the Apple Upgrade program. You're not the first to experience this as I've heard of this happening a time or two. Have you already talked with Apple about this? They need to update everything on their end to close out the billing for the previous iPhone.
